Review: The sound is good - The sound is good
Review: Todo muy bien, es la segunda que compro a un muy buen precio menos de 3000. Buena calidad. El diseño es genial, el par se escucha increíble, le falta un poco de profundidad en bajos, pero con las 2 se soluciona. La segunda me llegó más de un mes después, pero valió la pena esperar por 2600.
